Appncatioa mea Mai-ch 2o, i913. serial No. 755,701.

To all ywhom 'it' 'may concern Be itknown'that I, JAMES B. MoDnvrrr, a citizen of the United States, residing at Chicago, in the county of' Cook and State of Illinois, have invented certain new and 1useful Improvements in Valves for Gasolene- Tanks, of which the following .is a specilication.

The valve which is the subj ect of thefpresent invention is designed for use in connection with gasol'ene tanks carried on motor vehicles, 'and its main object is to provide an improved-valve mechanism whereby the driver of the car may be Warnedof theI condition .of the gasolene supply before the latter is entirely exhausted, the mechanism being constructed so that the feed of the gasolene is limited to' apredetermined depth, after which no moregasolene will flow to the carbureter, thus giving the driver notice that the fuel supply is low and that replenishinent i5 necessary, and also to allow the feed'of the remaining contents of the tank.

The normal supply of gasolene to the carbureter is vtaken from the tank some distance above the bottom thereof, so that a supply of pure gasolene is assured, the Water, solid matterv and' other impurities settling in that portion of the 'tank which is below the-level from which the normal supply is obtained.

Gther objects and advantages of the in- 4 vention will vbe pointed out in the detailed description appearing hereinafter, reference being had to the accompanying draw'- ing in which a vertical section of a fragment of the tank and the valve mechanism is shown. f

Referring specifically to the drawing, 5 denotes the bottom of a tank such as is used on motor vehicles vfor holding the Supply of gasolene which is employed as the engine stem 9 has a longitudinalchannel 10 ex' tending throughout its entire length, the upper end of said channel opening through the corresponding end of the stem. The

channel is ycontinued through thebody `portion of the "valve casing up to the bore 7.

In the. stem 9 is also a second channel 11 extending parallel to the channel 10 but opening through the side of the stem at the tank bottom. This channel 11 also extends to the bore 7. Y Y.

Below the body portion 6, the valve casing is formed with a cup 12 having a removable bottom portion 13 provided with a drain valve la.

'From 'the body portion G an outlet nozzle 15 extends into the cup 1Q, said nozzle being in alinement with the channels 10 and 11 and extending from the bore'7.

The plug 8 is` an ordinarytapered turning plug having transverse ways 16 and 17 respectively arranged at a right angle to each other. The way 16 is adapted to register with the channel 10 and the Way 17 with the channel 11. Both ways are adaptedto register with the nozzle 15. Thus, when the y plug is turned to bring the way 16 in alinement with the channel 10, the channel 11 is' shut off and gasolene flows from the tank bythe way of the channel 10 and the nozzle 15 into the cup 12. When the plug; is turned to place the Way 17 in alinement with the channel 11, the channel 10 is shut oi, and gasolene flows from the tank by the way of the channel 11 and the nozzle 15 into the cup 12. The valve plug has a stop 18 similar to the stop employed in connection with gas cocks, to'prevent the. plug from being turned more than a quarter revolution. The diameter of the ways 16 and 17 is less than that of the channels 10 and 11, so as to allow aline- 'ment with the latter if the plug should wear in the direction of its length.

in the side of the cup 12, above the bottom thereof and the mouth of the nozzle 15, is an opening into which is screwed a cap 19 having onits outer face an angular portion 20 to facilitate the application of a wrench,

.and a nipple 21 to which is connected, by

means of an ordinary coupling sleeve 22, a pipe 23 leading to the. carbureter .(not shown).- The pipe 23is provided with a valve 24.. The inner portion ofthe cap 19 carries a screen 25;.tae1iclude .solid matter l and othervimpuriti'es `trom the pipe 23.

The' Ag'asolene vwhich is discharged from the 'tank into/the" cup 12, Hows out of the same through uthe `cap 19 and is carried `,by

the pi'peQB to the carburetor. Inasmuch `as the` outlet qfthefcnp is above thebottoiii.-J1o

yiie'reof, impurities have a chalice to settle @ind will n ot ass through the outlet. If any impurities s ould .rise to the outlet, the reen 25 will prevent their entrance into the ipe 23, and as the screen is vertical such impurities will slide down the same and irepjback to the bottom of the cup.

,lvhecup v12 can be easily cleaned by removing the bottom portion 13.

v the valve plug 8.-

":end between a cap 28 and the corresponding` when the The valve plug 8 is held wedged to its seat by a spring 27 coiled around one projecting side of the body portion 6 of the valve cas- ,anglA The other end .of the `valve plug has a handle 29.

It will be evident from the foregoing that a supply of puregasolene to the carbureter is assured, and the driver is ,also warned gasolene level is getting low. In use, the valve plug 8 will be Vturned to shut if he'. channel I1 and to open the channel 21),; "Thus, the gasolene continues to flow until its. level reaches the upper end of the stem A9?, and the ow will then cease. 'supply to replenish the tank is not at hand,

4and an outlet nozzle the driver then turns the valve plug so'as'30 to open the channel 11, whereupon the gasolene continues to flow from the tank until the latter is empty, thus giving the driver` time to run the car to a place where a new supply 'of gasolene may be obtained.

I claim: V

The combination with tank; of a valve casing connected thereto and comprising a solid body portion having a transverse bore depending therefrom, said body portiony having a stem extending into the tank, said stem having channels the inlet ends of which are at diilerent levels in the tank, a cup extending from the body portion, into which cup the nozzle discharges, said cup having an outlet, and aro-y tatablevalve plug in the aforesaid bore, said valve plug having transverse Ways which are alternately in alinement with the aforesaid channels to open the same to the nozzle, 50 one channel being closed when the other channel is open, and vice versa.

In testimony whereof I ailix my signature in presence of two witnesses.
